vFIELD, a citizen of the United States, and resident of the city ofProvidence, 1n the county of Providence and State of Rhode Island, haveinvented certain new and useful Improvements in Lacing-Stud-SettmgMachines, of whichthe following is a specification.

This invention relates to improvements in machines for automaticallysetting lacing studs suchas hooks or eyelets in shoe uppers, and has forits. object to provide means adapted to work in conjunction with such amachine for feeding a strip of reinforcing tape to the shoe upper to beconnected to the upper by the setting of the lacing studs thereinto,this tape to serve as a support, reinforcement or backing for the thinupper about the stud to prevent the latter from pulling out. 1

A fu her object of the invention is to rovide means in the work feedingmeans or engaging and feeding or advancing the tape in unison with theupper.

A further object of the invention is to provide means for severing thetape into predetermined lengths or into a length for each individualstud if desired, whereby the tape is caused toreadily take the naturalform of the upper, and lie flat thereon with-.

out wrinkling or buckling.

With these and other objects in view, the invention consists of certainnovel features of construction, as will be more fully described andparticularly pointed out in the appended claims.

up the shoe, reinforcing strips of this character have heretoforebeenput by a separate hand operationto conform to the shape or contourof the outer edge of the upper and must be positioned by hand of theoperator: and fed at the time of feeding the work to the machine. Thisoperation of cutting the strips'and feeding them to the machine by handrequires extra time and adds considerable to the cost of constructin theshoe upper. I To obviate this. difficulty I have providedacomparativelynarrow ta e, but of a sufficient width to form a suita lereinforcement for the lacing studs, and I feed this strip of tapeautomatically from the reel to the shoe upper, preferably by themechanism that feeds the upper, and in order to prevent this tape frombuckling or wrinkling which would be the case if caused to bend edgewiseto take the shape of the curve about the edge of the upper, I simplysever the tape, or cut from the ribbon a separate piece for each stud,whereby these short pieces serve as reinforcing pads and each pad isautomatically secured in position by the setting of its stud. By the useof my improved reinforcing tape and the mechanism for feeding the same,the work of preparing the strip by cutting it to shape is entirelyeliminated, the work of positioning and feeding by hand is alsoeliminated and the total cost of preparing and positioning thereinforcing member is reduced to the minimum.

I have shown and described one form of mechanism for feeding, severingand con meeting a ribbon or tape to the shoe upper, but any othersuitable means may be employed for this purpose without departing fromthe spirit or scope of my invention. Y
